It’s
easy for just about any company that wants to attract customers to
say they’re quality focused. After all, quality is what customers
want. It’s the biggest marketing buzzword out there, and it’s no
mystery why. If you’re relying on accurate data to drive call rating
and routing applications in the telecom industry, poor quality can
cost you Big Time.
With the requirement for accuracy being paramount in our field, what
vendor wouldn’t want to be known as the high quality vendor?
Tele-Tech is no exception. For three decades we’ve been defining
quality, leading the way with rigorous standards and continuous
improvement processes. Clients repeatedly tell us our data is
top-notch, and over the years, we’ve been satisfied with this rather
subjective feedback. But now, we can do something other vendors
can’t. We can prove our accuracy is superior and provide the
statistical information to back-up our claims.
The question that started it all.
Quality can be claimed by just about anyone. Quality can be preached
by people with decades of experience, or heralded on the web site of
a company that’s only been around for a few days. But, saying you’re
quality focused doesn’t necessarily make it so. Which lead me to
wonder, can accuracy be proven in our environment?
And thus began my journey…
In a world full of exaggerated claims and meaningless assertions, I
set out to prove first to myself, and then to the industry at large
what our long-time customers already know. Tele-Tech really is at
the top of the game when it comes to data accuracy.
I began zealously dissecting the accuracy information we had
collected to date, crunching the numbers that my operations and
customer service teams were tracking. What I found was impressive.
The Good
The numbers available then were based on internal error checking.
They showed how many data files were found to have one or more
errors during our strict quality control processes. Using the number
of errors and the number of data files included in our products, a
bit of simple arithmetic showed our accuracy percentage to be 99.75.
Now keep in mind that the 0.25 percent of files in our database that
were found to be in error during the quality assurance process could
be corrected before they were ever delivered to clients, resulting
in a near perfect database upon release. It was 2001, and this was
really leading edge for our market niche. We were the only company
out there providing any statistical information to prove our data
quality.
I was pumped up! I was like a pocket-protector-wearing statistician,
eager to see what the numbers would show with a bit more analysis
(which isn’t easy for someone who hasn’t added more than two numbers
together without a calculator since 1989). I knew I needed help
finding more meaningful statistics.
“What you’re missing here,” I was curtly informed by the true
pocket-protector wearers in my company, “is information on how many
customer complaints show that an error did in fact get through the
quality control process.”
“OK. Right!” I thought. We do on occasion have customer questions
that when investigated, show an error in the delivered data. I set
to work, determined to ensure my statistics were valid and as
accurate as our database itself.
But while my new direction on the stats
seemed logical, I soon
uncovered a problem. I couldn’t find historical information on how
times we’d corrected and reshipped data to customers.
Back to the techies I went. “Hey, can you guys give me some info on
how many times we’ve had to correct data and reship to customers due
to errors?” I asked.
“That doesn’t happen too often,” was the response I received, “So
we’ve never tracked that.”
I was devastated. A true flaw in my quality measurements had been
exposed, and the adjustment that would validate the data I’d been
gathering for a year was not in site. I was at a crossroads, but
failure was not an option. I pressed on.
As a team, we started tracking the reworks and recalculating our
statistics to show the number of customer found errors reported
each month versus the number of file changes implemented in the
month the report of the error was made. This method of calculating our
accuracy was much tougher on us because we were including only files
changed that month in the equation as opposed to all files in the
database. But it was a truer picture of the quality of the data when
customers receive it.
After a year of tracking this data, we arrived at 2003 with our
accuracy looking something like this...
Our efforts to measure our quality were on a roll! Customers and
prospects were impressed with our data and with the fact that we
could measure accuracy in the first place! Our operations teams were
happy with the specific performance standards. And I was working it
from the sales and marketing side!
The Bad
Then, perhaps cocky from the results of my efforts to date, I made
an announcement at a management meeting that will live in infamy. I
was proud about what the stats reflected, and as a marketing
professional, I was enticed by the idea of raising the bar on data
quality in our market niche.
“What we really need in order to prove how good we are,” I said,
with a bit too much confidence, “is a Service Level Agreement. A
guarantee, if you will, that really shows we stand behind our
quality.”
The reaction I got was…
Complete silence.
And then came the barrage of questions and comments for which I had
no reply.
“How do you know whether your statistics are calculated in a valid
way?”
“What data would be included in the guarantee?”
“Are customers really asking for this?”
“If we’re going to do this, we need to do it right.”
That’s when I realized I was in over my head.
The Big Q
Enter Tom Redman, data quality expert extraordinaire.
Dr. Redman established the AT&T Bell Laboratories Data Quality Lab
in 1987 and led it until 1995. There he created the Applied Research
Program that produced many of today's methods for improving data
quality and saved AT&T tens of millions of dollars. He is the
leading inventor of practical techniques to help organizations
improve amidst the explosion of data (and data quality problems)
created in the information age. In short, Dr. Redman lives and
breathes data quality day in and day out. (He says this condition is
not fatal. We sure hope he’s right!)
At our first face-to-face meeting with our new quality guru, he set
us on a dizzying course to measure our accuracy in a statistically
legitimate way. “You just need to be driven by the ‘Big Q’, ” he
said.
Tom stressed we should calculate quality using the most stringent
measurements available because of the level of quality we’d achieved
to date and because accuracy was so important to our customers. When
Tom says “stringent”, we found that he doesn’t really mean the
dictionary definition of stringent, which is “Imposing rigorous
standards of performance; severe.” No. What our data guru actually
means by stringent is that we should employ standards higher than
Six Sigma, the well known, rigorous, and disciplined methodology
that uses data and statistical analysis to measure and improve
quality.
So reluctantly, rather than measuring the number of incorrect bytes
in a given data set, or the number of incorrect fields as Six Sigma
standards would require, we began measuring the number of incorrect
files received by customers against the number of files that were
changed. If one teeny-tiny byte in a file with 1700 fields is wrong,
we consider the entire file wrong. Any error, omission, or typo that
makes the file imperfect in any way means the file is wrong. Period.
Next, we started a more thorough tracking of the changes we made.
When a customer reported an error, and the report was proven valid,
we could count the error in the month it was made instead of the
month in which it was reported, producing a more concise
measurement. Seems reasonable, but there is a catch. If a customer,
in January of 2006, finds 8 zillion files that are incorrect, and we
trace the error back to a tariff interpretation problem in January
of 2005; then suddenly, a month that had previously been stellar on
our graph for a year could now shift to a very dim month indeed. In
essence, we created a moving target.
The results of these changes in our measurements are shown in this
graph:
Goal #1 With our measurement parameters in check, we started to set
objectives for increasing our accuracy percentage.
Our first goal is
to eliminate what came to be known as the “bad” months. (You can
spot the “bad” months pretty easily on the chart. I hope that’s
enough said about that.) In studying the months that fall into this
category in the past three years, we determined that in each case,
the cause was a single error, multiplied by a large number of files.
In fact, in all cases, the “bad months” were created by errors that
effected just one client. Generally, these problems were human
errors that can be corrected by taking staff members out back and
beating them with a …wait… I mean they can be corrected with
additional training and additional automation. We set out to
eliminate those bad months by:
1. Adding more quality control measures to our delivery procedures.
(It seems that in some cases, “bad” months were the result of not
shipping all files to a customer, even though the files themselves
were accurate. The new quality controls in our delivery processes
are designed to prevent a recurrence of this “shooting ourselves in
the foot” syndrome.)
2. Undertaking a thorough post-mortem review of errors to gain a
full understanding of cause, effect, and potential preventative
measures.
3. Locating opportunities to move the quality effort forward in the
process to avoid errors in the first place.
4. Creating a plan to
eliminate tariff interpretation errors by
providing additional training, including:
a. On-going weekly training sessions for local researchers to
discuss tariff exceptions, unique circumstances, and new tariff
concepts, as well as special techniques or information discovered
during data maintenance.
b. A six-month thorough review of our procedures manual including
modifications, additions, and deletions on all procedures. This
manual includes detailed instructions on over 100 separate processes
undertaken to produce our databases.
c. Ongoing “Mock Calling Area Exercises”. No, these are not sessions
where we make fun of the calling areas while doing jumping jacks.
These are our version of the “Top Gun” school for fighter pilots,
where the best of the best come to get better. In these exercises,
local researchers are given copies of actual data files that have
been changed in a test environment to recreate previous errors. The
researchers are challenged to find and correct the errors. Trick
questions are allowed, which offers an explanation for the ghoulish
laughter we hear coming from the office of the twisted soul who
mucks with the data to make the Mock Calling Areas in the first
place.
5. Reviewing errors found during the quality control process for
ideas on additional automation to eliminate human errors.
Future Goals
Once we’ve gone a whole year without a “bad” month, we’ll check off
that goal and use the current accuracy statistic as our first
benchmark. At that point, we’ll put our next goal into effect:
Cutting our error rate in half each year. So if our accuracy rate
proves to be at 99.95% when the bad months are eliminated, our goal
for the subsequent 12 months will be 99.975%.
This is an ongoing process. And
we pledge to report these statistics
to you monthly via our web site. (Unless they’re really bad.)
No, we’ll do it every month regardless of the results. We are human
and we do occasionally make mistakes. But mistakes are also
opportunities for us to further refine our quality assurance
processes and eliminate future errors.
The Reward
What this means for clients is that you know what you’re getting,
and what you’re paying for. It means you can trust Tele-Tech as your
sole-source provider because you know our level of accuracy.
And while producing data this good generally means we’re not the
lowest priced vendor on the surface, we do offer the lowest total
cost.
Lowest Total Cost & Dr. Redman’s Rule of Ten:
“For every dollar it costs you to do work when the data you receive
is perfect, it costs $10 to do that work when the data contains
errors.”
In fact, Tom has calculated that poor quality data costs the typical
organization 20% of revenue. That’s no laughing matter. Can your
organization afford poor quality data, even if it’s less expensive
initially?
Freedom from data errors means the cost of doing your work will be
90% less than the cost of doing that work with an inaccurate data
source.
Freedom from data errors means you can free up 20% of your revenue
for investment in other things.
Freedom from data errors means the bills you generate are accurate,
causing fewer costly customer complaints and billing disputes, and
fewer refunds and credits.
Let Freedom Ring, Baby!
It Comes Full Circle
But back to my Service Level Agreement (SLA), the reason we brought
Tom here in the first place. How can we validly define our accuracy
and set-up a meaningful guarantee for our customers? When would he
answer the barrage of questions I was thrown that fateful day at our
management meeting? Aren’t those his problem now (I hoped)?
That’s when Tom made a bold, if not revolutionary statement. He
shared with us what he had discovered after consulting for numerous
customers of data vendors.
“Customers don’t want their money back,” he stated. “A small
fraction of fees returned if the data is wrong is meaningless.
Customers just want the data to be right the first time.”
Wow! Talk about a “back-to-the-basics” approach! Tom stated the
obvious that we’d been overlooking in writing an SLA.
Tom convinced us that our SLA should be
reward based, not penalty
based. But the reward’s not for us when we do a good job. After all,
that’s what you pay us for. The reward is for you when you find an
error.
Introducing…Let Them Eat Cookies!
It’s a big bonus for us when a customer reports a suspected error.
In seventy percent of these cases, our data is proven correct. But
when the investigation spawned by the report does turn up an error,
we get to correct it and make our database even stronger. It also
gives us more ammo with which to train our Top Guns and keep them
sharp.
When you suspect an error in our data, email our Cookie
Hot-Line at
cookies@telecomdb.com. If we did, in fact, deliver
flawed data, we’ll send you a box of goodies from the
world-famous Charleston Cookie Company right here in Charleston,
South Carolina. Trust me; these are better than Mom’s double
fudge-peanut butter-chocolate chip cookies. (Sorry Mom!)
In addition, as our quality initiatives continue, we’ll be working
on developing more traditional SLAs that will focus on what
customers time and again tell us are the most important attributes
of our service: 1) data accuracy; 2) help desk results; and 3)
on-time delivery. Once our goal of eliminating bad months is reached
we’ll have a baseline on which to develop further customer
assurances.
Does all this seem like overkill?
Well, maybe to an outsider. But from my perspective, absolutely not!
As a small, family-owned company generating revenue solely from the
data we provide to the industry, we know that our business lives and
dies, literally, by the accuracy of the data we deliver.
While we are a micro company by telecom industry standards, the
biggest players have come to rely on us. Our data is used to
determine billing on billions of landline and wireless calls each
month. A small error becomes enormous in the robust environment in
which our data resides. It is precisely because of this that we
insist that our customers’ experiences with our data are virtually
perfect. We have learned to be continuously driven by the “Big Q”.
